ABSTRACT
Obstructive sleep apnea (OSA) is a sleep disorder resulting from the repetitive narrowing and collapse of the upper respiratory tract. The results of previous epidemiological studies confirm a significant impact of OSA on the health situation around the world. Untreated OSA is associated with many adverse health effects, such as hypertension, coronary artery disease, stroke, atrial fibrillation, congestive heart failure, and daytime sleepiness. Excessive mortality of OSA patients, especially in men under 50 years of age, associated with advanced disease, obesity, cardiovascular complications, and a greater risk of road accidents, requires an urgent extension of the diagnostic-therapeutic database dealing with this problem. It is estimated that in the adult population, OSA occurs in 4% of men and in 2% of women. In recent years, intraoral devices have become an increasingly common method of OSA and snoring treatment. Nevertheless, the use of devices producing continuous positive airway pressure (CPAP) remains the most effective treatment method. However, intraoral devices have the advantage of not requiring a source of electricity and are less troublesome in everyday use. Intraoral devices are well tolerated by the majority of patients, and their therapeutic efficacy is confirmed. Since such devices become commoner, the purpose of this work was to present the procedures, indications, and recommendations involved with intraoral devices while taking into consideration a variety of dental conditions. The side effects of the use of intraoral devices and their influence on the entire stomatognathic system were also described.

Obstructive sleep apnea (OSA) is defined as episodes of upper airway obstruction occurring during sleep. Conservative treatment of OSA consists of continuous positive airway pressure (CPAP). An alternative treatment in mild-to-moderate OSA could be the use of intraoral mandibular advancement devices (MAD). The aim of this study was to evaluate therapeutic efficacy of MAD in OSA patients intolerant to CPAP. The study group included 8 patients, who fulfilled specific inclusion criteria during a dental examination, out of the 30 CPAP intolerant patients who were referred for the possible use of MAD. The selected patients used MAD for 30 days and then switched to CPAP for 10 days to compare the effectiveness of both treatment methods. They had 3 polysomnographic (PSG) examination: baseline before treatment, and at the end of MAD and CPAP. We found that either treatment method resulted in comparable symptomatic improvements in OSA patients. In detail, the apnea-hypopnea index decreased, along with the overall number of obstructive, central, and mixed apneic episodes during sleep time. The mean arterial oxygen saturation (SaO2) improved and the minimum SaO2 level noted during night time got enhanced. Differences in the sleep apnea indices after MAD and CPAP treatments were insignificant, but there was a consistent impression that CPAP was superior to MAD as it tended to improve symptoms to a somehow greater extent. We conclude that MAD is a sufficiently effective treatment alternative for OSA patients who are intolerant to CPAP or in whom CPAP therapy fails.

Obstructive sleep apnea (OSA) is defined as episodes of upper airway obstructions during sleep. The method of choice in conservative treatment of OSA is the use of devices that produce positive airway pressure (CPAP). In patients with mild-moderate form of OSA, intraoral mandibular advancement devices (MAD) are applied. The aim of the study was to evaluate the therapeutic efficacy of MAD in patients with severe OSA who were unable to use CPAP. In this preliminary study three patients from a group of 25 severe OSA sufferers who failed to use CPAP, were included. The three patients underwent a triple polysomnographic (PSG) investigation: on CPAP, before MAD treatment, and during MAD. The patients completed the Epworth Sleepiness Scale questionnaire twice. We found significant improvements of subjective symptoms and PSG-evaluated variables after application of MAD in all three patients in comparison with both baseline and CPAP-recorded data. We conclude that MAD can be an alternative treatment option for severe OSA patients who are non-compliant with CPAP therapy.

Yeast-like fungi and gram-negative bacilli are the most frequent potential pathogens of the respiratory tract isolated from the denture plaque of patients with chronic obstructive pulmonary disease (COPD). Dominant species among yeast-like fungi are Candida albicans and Candida tropicalis. Significant frequency is also exhibited by Klebsiella pneumoniae and Klebsiella oxytoca. The purpose of this study was to analyze genetic diversity of the strains of C. albicans, C. tropicalis, and Klebsiella spp. present in patients in stable phases of COPD. The analysis was conducted by the random amplified polymorphic DNA (RAPD) method on clinical strains isolated from patients with COPD and control patients in overall good health. Forty one strains of Candida albicans, 12 of Candida tropicalis, as well as 9 strains of K. pneumoniae and 7 of K. oxytoca were scrutinized. The dominant species in clinical material from COPD patients was Candida albicans with a substantial degree of variations of genetic profiles. On the basis of affinity analysis, 19 genetic types were identified within this strain. An analysis of the banding patterns among C. tropicalis strains indicated the existence of 6 genetic types. A considerable diversity of genetic profiles among Klebsiella spp. also was established. The genotype diversity of Klebsiella spp. strains may indicate the endogenic character of the majority of infections, regardless of the therapy applied for the underlying condition.

A combination of abnormal anatomy and physiology of the upper airway can produce its repetitive narrowing during sleep, resulting in obstructive sleep apnea (OSA). Treatment of sleep-breathing disorder ranges from lifestyle modifications, upper airway surgery, continuous positive airway pressure (CPAP) to the use of oral appliances. A proper treatment selection should be preceded by thorough clinical and instrumental examinations. The type and number of specific oral appliances are still growing. The mandibular advancement appliance (MAA) is the most common type of a dental device in use today. The device makes the mandible protrude forward, preventing or minimizing the upper airway collapse during sleep. A significant variability in the patients' response to treatment has been observed, which can be explained by the severity of sleep apnea at baseline and duration of treatment. In some trials, patients with mild OSA show a similar treatment effect after the use of CPAP or MAA. It is worthwhile to give it a try with an oral appliance of MAA type in snoring, mild-to-moderate sleep apnea, and in individuals who are intolerant to CPAP treatment.

Morphological and functional disturbances induced by postsurgical defects and loss of tissues in the stomatognathic system due to the treatment of tumors in the maxillofacial region determine the therapeutic needs of patients. The study aimed at clinical and epidemiological evaluation of patients under prosthetic treatment in order to establish the algorithm for rehabilitation. The study group was composed of the patients after midface surgery (45.74%); surgery in a lower part of the face (47.38%); mixed postoperative losses (3.44%); loss of face tissues and surgery in other locations in the head and neck region (3.44%). The supplementary treatment was applied in 69.63% of patients. Clinical and additional examinations were performed to obtain the picture of postoperative loss, its magnitude, and location to plan the strategy of prosthetic rehabilitation. The management algorithm for prosthetic rehabilitation in patients after surgical treatment of maxillofacial neoplasms was based on its division in stages. The location and magnitude of postoperative losses, as well as the implementation of supplementary treatment of the patients after treatment of maxillofacial tumors, influence the planning of prosthetic rehabilitation that plays a key role and facilitates the patients' return to their prior living situation, occupational and family lives.

ABSTRACT
As a consequence of surgical treatment of maxillary tumors, a connection between oral and nasal cavities is formed, which leads to serious functional disorders, manifested by inability to normally ingest food, proper speech articulation, and to respiratory route disorders and upper airway inflammation. These morphological and functional disorders are intensified by adjunctive radio- or chemotherapy. The aim of this paper is to present different possible methods of rehabilitation, including application of interim obturators and individually planned prosthetic restorations to improve respiratory efficiency in patients after extensive maxillary resections. In the course of prosthetic treatment, cooperation with the laryngologist to consider every aspect of chronic paranasal sinusitis, accompanied by concurrent inflammation of oral, nasal, or laryngeal mucous membranes, was of paramount importance. Based on the quality of life questionnaire, used in this study, evident improvement in the masticatory efficiency, speech articulation, and respiration was observed. Particularly good effects were obtained in edentulous patients, in whom implant-prosthetic treatment was possible to apply. Comprehensive and multidisciplinary care of postoperative patients greatly contributes to their better quality of life and facilitates their return to prior living conditions, as well as to occupational and family lives.

Obstructive sleep apnea (OSA) syndrome is a sleep-related breathing disorder, due mainly to peripheral causes, characterized by repeated episodes of obstruction of the upper airways, associated with snoring and arousals. The sleep process fragmentation and oxygen desaturation events lead to the major health problems with numerous pathophysiological consequences. Micro-arousals occurring during sleep are considered to be the main causal factor for night jaw-closing muscles activation called bruxism. Bruxism is characterized by clenching and grinding of the teeth or by bracing or thrusting of the mandible. The causes of bruxism are multifactorial and are mostly of central origin. Among central factors there are secretion disorders of central nervous system neurotransmitters and basal ganglia disorders. Recently, sleep bruxism has started to be regarded as a physiological phenomenon occurring in some parts of the population. In this article we present an evaluation of the relationship between OSA and sleep bruxism. It has been reported that the frequency of apneic episodes and that of teeth clenching positively correlates in OSA. However, clinical findings suggest that further studies are needed to clarify sleep bruxism pathophysiology and to develop new approaches to tailor therapy for individual patients with concomitant sleep bruxism and OSA.

Oral inflammation is an important contributor to the etiology of chronic obstructive pulmonary disease, which can impact patient's health status. Previous studies indicate that people with poor oral health are at higher risk for nosocomial pneumonia. Denture wearing is one promoting factor in the development of mucosal infections. Colonization of the denture plaque by Gram-negative bacteria, Candida spp., or other respiratory pathogens, occurring locally, may be aspirated to the lungs. The studies showed that chronic obstructive pulmonary disease (COPD) patients treated with combinations of medicines with corticosteroids more frequently suffer from Candida-associated denture stomatitis. Treatment of oral candidiasis in patients with COPD constitutes a therapeutic problem. Therefore, it is essential to pay attention to the condition of oral mucosal membrane and denture hygiene habits. The guidelines for care and maintenance of dentures for COPD patients are presented in this paper. The majority of patients required improvement of their prosthetic and oral hygiene. Standard oral hygiene procedures in relation to dentures, conducted for prophylaxis of stomatitis complicated by mucosal infection among immunocompromised patients, are essential to maintain healthy oral tissues. The elimination of traumatic denture action in dental office, compliance with oral and denture hygiene, proper use and storage of prosthetic appliances in a dry environment outside the oral cavity can reduce susceptibility to infection. Proper attention to hygiene, including brushing and rinsing the mouth, may also help prevent denture stomatitis in these patients.

Studies suggest an association between orofacial pain, accompanying temporomandibular disorders of myogenous origin, and headache, especially its tension-type. The occlusal appliance therapy is one of the options for the treatment of orofacial pain due to masticatory muscles tenderness. The aim of the present study was to assess the effectiveness of occlusal stabilization splint therapy in myofascial pain and tension-type headache in patients with sleep-disordered breathing. Forty three such patients were enrolled into the study group. The patients were treated with stabilization occlusal splint of vertical thickness at vertical jaw separation, established individually for each patient using a cephalometric analysis. The intensity of orofacial pain (numeric rating scale) and headache (analog rating scale), frequency of headache (%), and jaw qualitative function were assessed at baseline and after 2 and 6 months. Medians of headache and orofacial pain intensity were reduced after 6 months of treatment compared with baseline: 6.0 vs. 2.0 (p < 0.0001) and 6.0 vs. 1.0 (p < 0.0001), respectively. Pain decreased below 3 score points in 61.8 % of the patients with headache (p = 0.23) and in 85.3 % of patients with orofacial pain (p < 0.0001). Overall, the improvement in both signs and symptoms of orofacial pain was observed 81.4 % of patients after using occlusal stabilization splint for 6 months. We conclude that occlusal stabilization splint was effective in reducing painful symptoms of temporomandibular disorders of myogenous origin, a frequent feature of sleep disordered breathing.

The diagnosis of temporomandibular joint (TMJ) disorders consists of clinical (Reaserch Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD) and additional (computer tomography, CT or magnetic resonance imaging, and MRI) examinations. Due to the growing knowledge of pathologic changes within the TMJ, the researches become more aware of the difficulty in detection the early symptoms of disorders using conventional examination. Therefore, it is now expected that the collected samples of synovial fluid, serum, or urine samples could enable easier identification of inflammatory process course, and degenerative cartilage changes state.

INTRODUCTION: Angiogenesis occurs under physiological and pathological conditions and is regulated by cytokines and growth factors. Vascular endothelial growth factor (VEGF) is a multifunctional angiogenic cytokine that plays a significant role in inflammation and immune responses implicated in the pathogenesis of inflammatory processes in the implant- surrounding tissues. OBJECTIVE: The study investigated the concentration of VEGF in gingival crevicular fluid (GCF) in healthy and diseased soft tissues surrounding implants. MATERIAL AND METHODS: Clinical examinations were focused on assessing the periodontal status of soft tissues around dental implants with the use of Florida Probe. Bone loss was examined radiologically. VEGF concentrations were assessed by enzyme-linked immunoabsorbent assay (ELISA). RESULTS: VEGF concentrations were found higher in crevicular fluid around implants than in clinically healthy sites. They were also strongly correlated with the pocket depth. CONCLUSIONS: The presence of VEGF in gingival crevicular fluid in patients with peri-implants can be implicated in the progression of peri-implantitis, possibly by promoting the formation of new blood vessels during angiogenic processes.
